It compresses only [[GIF]] image files, to its native '''.GPS''' format. It was developed by John Callicotte, and distributed as shareware. <br /> <br /> A GPS file can be decompressed back to a GIF file that is functionally identical to the original, but not necessarily byte-for-byte identical.<br /> <br /> == Format details ==<br /> There's clear evidence that Gifpress uses the Cx data compression toolkit (v2.01) by Eugene Nelson and Four Lakes Computing ({{CdTextfiles|psl/pslmonthly25/dos/prgmming/cx201e.zip|cx201e.zip}}).<br /> <br /> == Identification ==<br /> It's not known how to identify a GPS file from its contents, though in limited testing, the bytes {{magic|0xff 0xb4}} always appeared at offset 2.<br /> <br /> == Software ==<br /> * {{CdTextfiles|pier/pier06/023/GIFPRESS.ZIP|Gifpress v1.0}}<br /> <br /> [[Category:Recompression]]</div>
